丁子湾位于黄海南部,海阳市海域的南端,20世纪80年代中国蛤蜊在此繁衍生息,资源非常丰富,单船日产量在1 000 kg左右,效益非常可观。由此,大量渔船投入此项生产和先进的捕捞工具,导致资源匮乏。自1998年起资源锐减,大量小型渔船停业或转产。1999年始,采取了休渔期管理,中国蛤蜊资源逐渐恢复,单船日产量300余公斤。此种贝类为低值水产品,价格低,完全以产量增加经济效益。1996年海阳市大山渔业技
Dingzi Bay is located in the southern part of the Yellow Sea and the southern part of the sea of Haiyang City. In the 1980s, Chinese clams multiplied and had abundant resources. The daily output of a single boat was about 1 000 kg and the profit was very impressive. As a result, a large number of fishing vessels have invested in this production and advanced fishing tools, resulting in a lack of resources. Since 1998, sharp reduction in resources, a large number of small fishing boats closed or converted. Since the beginning of 1999, the fishing moratorium has been adopted, and the resources of clam in China have been gradually restored. The daily output of a single boat is over 300 kg. Such shellfish for low-value aquatic products, the price is low, increase economic output completely. 1996 Haiyang Fisheries Technology
